T all whom/fit may concern:

Be it known that I, FRANK E. 'KRESS, a citizen of the United States of America, residing at the city and county of Denver and State of Colorado, have invented a new and useful Brush M-aking Machine, of which the following is a specification.

My invention relates to improvements in brush making machines for automatically filling the backs of brushes with bristles; and the objects of my invention are: First, to provide a machine that will automatically fill one complete row of bristles, hair or any other suitable material used for brushes, into metal, composition, or wooden brush backs. Second, to provide a machine for automatically filling twelve bundles of bristles, hair or. any other suitable material used for brushes, at one revolution of the machine, also wiring the twelve bundles complete. Third, to provide a machine for separating the required amount of bristles, hair or any other suitable material used for brushes, for making twelve full separate bundles, these being then gripped by the gripper and carried to the proper position by the gripper holder and inserter guide,

the twelve bundles to be then inserted by the twelve inserters or the gang inserter. I attain these objects by the mechanism illustrated in the accompanying drawings, in which: ,1

designates a base-plate which is provided with apertured bolt or lag-screw receiving lugs 2, by which it may be secured to a suitable foundation block or .to a substantial bench. Upon this base-plate I mount a pair of standards 3 and 3 which extend vertically up from the base-plate, and may be cast integral with the base-plate or may be detachably secured to it. I preferably detachably secure them to the base-plate by bolts 4. These standards are positioned a few inches apart, and they are each provided on their front end portion with a slideway 5. These slideways comprise vertically arranged finished step portions 6, which are formed on the front edges of introverted lugportions "7, which are formed on the front end of the standards. A gib 8 is removably secured to the front of each standard by cap screws 9, which together with the finished step portion in the lugs forms a square shaped guide slot in each lug. In these slide-ways I reciprocably mount a cross-head 10. This cross-head comprises a substantially square shaped casting provided with enlarged vertical side edges, which are finished to slide reciprocablyin the guideways of each standard.

' This cross-head is provided with a central i to be lifted out of the bearings when neceslug 11 at its upper end, which is divided by a slot 12 into cars 13, through which a pivotal pin 14 extends. One end of a connecting rod 15 fits in the slot 12 between the two cars, and is secured to them by the pin 14, which extendsthrough them. The opposite end of this connecting rod is pivotally connected to a double sided crank-arm 16, by a pivotal bolt 17, which extends through the crank arm and the end of the connecting rod. The two crank armsthat.

sary.

A cam 22 is mounted on thd crank shaft I on the inside of the standard 3, and between its bearing 20 and the crank-arm 16, which engages a roller 23, that is housed in one-end of a rock-arm 24, which is pivotally secured intermediate of its ends by a bolt 25, to the inside of the standard. The opposite end of this rock-arm is pivotally connected to one end of a lever 26, the opposite end of which is pivotally connected to one end of 'a projecting In 27 that is cast on a hub 28, which is provi ed at each end with a stubshaft 29 which extends through bearings 30 formed on the standards below the crosshead guideways 5. A cam 31 is also mounted on and is secured to the crank-shaft 18, on the inside of the standard 3, and between it and the crank arm. This cam 31 engages a roller 32, that is rotatably mounted in one end of a lever 33, which is mounted in a slideway block 34, which is bolted on the inside of the said standard. The opposite end of this lever is pivotally secured to'a projecting lug 38. that is formed on the hub 28. This hub 28 is provided with a projecting plate portion 39, which is arranged and adapted to be moved reciprocably from a vertical position to a horizontal position, and upon the outer edge of this plate portion 39, a gripping and holding mechanism is secured, which is arranged to receive the bundles of bristles from a bristle separating shuttle, and a bundling comb, which are arranged to separate the bristles from the hopper, as will be explained more fully hereinafter.

On the crank shaft outside of the bearing of the standard 3", a disk 40 is mounted and secured. in which a laterally moving spring controlled pawl 41 is mounted, and engages the ends of two arms 42 and 43, the function of which will be explained more fully hereinafter. The pawl 41 however acts to automatically couple the crank shaft to a suitable registering coupling disk or device, which may be driven by an electric or any other suitable motor. I do not illustrate the power driven part of the coupling or the motor, as they do not comprise any part of my present invention. 1

The crank shaft 18 extends beyond the journal box 20 and a cam 42 is mounted on and is secured to it. This cam comprises a hub of metal having a spiral groove 42*, formed in its peripheral surface, along the larger portion of its length, which is ar-' ranged to give a horizontal traveling movemerit to a pin 43 that fits loosely in it and that is secured in one end of a rock arm 44, which is pivotally secured by a pin or bolt 45, to a bracket 46, that is secured to the side of the standard. The opposite end of this rock-arm is bifurcated to form a slot 48 which fits loosely over a headedpin 49, that is secured to the rear end ofa separator bar 50, which is slidably mounted in a laterally extending arm 51, in which a slideway 52 is formed, that is adapted to receive the shuttle-bar, which is arranged to reciprocate in it. The inner end of the bar 51 has a rearwardly extending portion 51', at right angles to the body of the arm, and is secured to one side of ahopper supporting frame 53, that is adjustablv secured by screws 54,'to stepped bearing strips 55,

- which is adapted to move across the disthat are formed on rearwardly extending bracket portions 56, that are preferably cast integral with the standards. The slot in the arm 51, in which the shuttle bar reciprocates,,'is preferably a T-shaped slot; and the shuttle bar is a thin ,strip of'metal that fits loosely and slidably in it, and the pin to which the bifurcated end of the rock arm -14 is secured, is attached to the rear end of the shuttle. The front end of the shuttle is provided with a. pointed terminal end which 1 term" the bristle separating point, and

charge end of a hopper 57, which rests in the supporting frame 53, and separate from the hopper .a thin layer of the bristles at each forward movement imparted to it by the spiral grooved cam and the rock'arm, The shuttle bar-is provided with an elongated rectangular slot, which is located close to its shuttle end, and in this slot I pivotally mount a bristle bundling plate 58,which I term the bundler, and which comprises a'strip of metal of the length of the brushes to be made, which is provided along its lower edge with wedge-shaped pointed teeth 59. This bundler receives the bristles from a comb 60', and this comb and bundler in the machine herein illustrated, would be the length ofthe brush to be made, and as the length of the brush would be the length of the brush back to which the bristles or hair is secured, this bundler is'made to receive the bristles from the comb, and is arranged and adapted to separate them into the number of bundles of bristles or hair required for the length of the brush back. This bun dler normally stands in a vertical position, and is arranged to be swung up into a horizontal position at the end of each forward s metal 65, which is pivota-lly secured to the adjacent side of the hopper supporting frame, by a screw 66, and its end that is connected to the pin 61 is provided with a bent end that is provided with a hole,

through which the pin 64 projects, so that jects far enough beyond the end of the rock arm to receive one end of a coiled contraction spring 69, the opposite end of which is connected to a screw 70, which is secured to the side of the hopper supporting frame.

The rod 67 extends through a slot 67 formed in th'e'inside surface of the right angled end'portion 51 of the shuttle supporting arm, and its free end rests close, enough to the lower edge of the bundler to engage and swing the bundler up into a horizontal position on its pivotal trunnions. The rod 67 is moved to do this in the following manner: hen the plate 39 of the hub 28 is moved from a horizontal position to a vertical position by the engagement of the cam 31 with the lever 33, an adjustable abutment screw 71 carried by said plate, engages the end of the push rod 61, which is positioned in its path and slides it rearwardly on its pin 63 a short distance, and as it moves back it carries with it the lower end of the rock-arm 65, which is connected to it and moves its top end to push the rod 67 against the bundler 58 and raise and hold it in a horizontal position; the object of this is to allow the bundler to divide with its pointed wedge shaped teeth, the thin layer of hair or bristles that the shuttle separates from the hopper, into small bundles or bunches as the points of its teeth when they move up through the bristles dividethem and separate the bristles between the points of each pair of adjacent teeth from those between the other points of the teeth, and these independent bunches. or bundles of bristles are still held .by their upper ends by the comb 60, and at their lower ends by a foot plate 72, that extends across the end of the hopper supporting frame and projects a short distance above its floor, Consequently the bundler divides the bristles into bundles and holds them momentarily in that position un; til they are seized by a gripping device, which is secured to the edge of the inserter guide or plate 39 of the pivotal hub 28, which device grips them and moves them over the brush back. The me hanism for gripping the bundles of bristles in the teeth ofthe bundler will be described hereinafter. As soon as the bundles have been gripped, the inserter guide 39 moves with the gripping mechanism away from the bundler and the push finger, the spring 69 draws the rod 67 away from engagement with the bundler and moves the rock-arm and push strip forward to their normal position ready to be acted on again by the plate 39 at its next upward movement 'to the bundler. bundler is drawn instantly down into its vertical ppsition by a coiled spring 7 5, which is mounted on a pivoted pin 76, one end of one end of the spring resting upon the The - is connected to a pin 77, carried by the adjacent end of the bundler.

The hair or bristles holding hopper of my improved brush making machine consists of three parts, namely the hopper supporting frame 53, which comprises a rectangular open top trough-shaped casting, that is secured to the bracket extensions of the standards, and extends rearwardly from them, an open top open ended hopper member 57, that fits loosely within the supporting frame and in which the bristles are placed, and that is preferably made of sheet metal such as sheet brass, and which is filled with hair or bristles that are stacked on end and which have previously been cut to the desired length, and a pressure feeding device 78, which I term a pressure feeder, that fits slidably within the hopper proper, and that is arranged to exert a constant pushing feeding-pressure against the bristles in the hop per. I preferably carry out this feature in the following manner: The pressure feeder 78 comprises a long casting member wh ch fits slidably in the hopper 57, and is provided with an end wall 79, that is of the same height as the hopper and faces the bristles in the hopper, and at the outer end of this pressure feeder I secure to it a bar 80, that extends a short equal distance beyond each side, and to each of its end portions I secure the end of a wire rope 81, which extends to and over a pulley 82, that is pivotally mounted on a pin 83, that is secured to the inside of the brackets of the standards, and to the end of each rope I secure a weight 84 that is heavy enough to exert a constant pressure of sufiicient force to keep the wall end of the pressure feeder forcing the bristles through the hopper as fast as the shuttle and bundler and the gripper takes them from it. I e

The comb 60 is provided with end strips 85, which are secured to the front end of the hopper supporting frame by any suitable means, preferably by being welded thereto.

' This comb 60 comprises a bar portion that extends across the end of the hopper, and this bar is provided with a row of wedgeshaped or saw teeth 87, that are formed along its inner edge, and that are arranged to face toward the interior'of the hopper, and this comb is provided with the'samenumber of teeth as the bundler is, and from the pointed end of each tooth a small round pointed prong of wire 88 projects for a short distance, the teeth and pointed prongs being arranged to project substantially in a horizontal plane and parallel with the bottom of the hopper, and they act to separate the bristles in the hopper, as the said bristles are moved by the pressure feeder between the said prongs and into the spaces between the saw teeth, where they are crowded into a narrowing wedge-shaped s ace, which bunches the top end portions 0 the bristles in bundles, and to that extent assists the bundler, at each forward movement or stroke of the shuttle.

Above the comb an adjustable'plate 89, which I term a feed plate, is mounted on screws 90, which are threaded loosely into smalh hubs 92, which are formed on the supporting strips 85 of the comb. The screws 90 are provided with large head portions, in .each of which a circumferential groove 91 is formed, dividing the head into two collar portions and leaving a small neck portion 94 between the collars. The feed plate is a thin strip of metal, which extends above the teeth. of the comb and close to them, and its opposite.ends are provided with slots 95 Which are arranged to fit over the necks 94 of the screws, thus supporting the ends of the plate between the collar portions of the heads of the screws. This feed plate is adjusted to allow bunches of even size to work into the teeth of the comb, by moving it slightly along the teeth of the comb by turning the screws 90, which should be adjusted to keep the bunches of bristles collecting between the teeth of the comb, as even in size as possible. This is accomplished by turning first one screw and then the other, until the desired adjustment is are operated by the cams 22 and 31 as above described. The plate 39 is provided at its free end with a bundle gripping and carrying device, and also with a bundle folding and receiving and a needle receiving guide plate. Inasmuch, however, as the bundle in each cycle of the machines movement before the needle guide is brought into use, I will describe it first, and it consists of the following instrumentalities, and operates in the following manner. This gripping device is" positioned on the extreme outer edge of the plate 39, and comprises a bar 94, which I term the fixed grip-bar. which is provided with a central longitudinal slot, so that the bar is U-shaped in cross section, as shown in Fig. 17. Upon its upper closed or solid edge portion, a plurality of teeth 95 are formed, each of which has a hook shaped terminal end projecting slightly toward the right hand side of the machine. The teeth and their books are allmade of the same size and shape and the hooks all project in the same direction. The slot in gripping and carrying mechanism operates the grip bar-rextends throughout its length from-its-nnderside, and'extends up through the hookedteeth to'clese-to their top edges.-

This. fixed grip bar is secured rigidly to the end of the plate by screws 96,-whichextend through its opposite ends,- and are threaded into. threaded ape tures formed in the ends of the ate-t0 =receiveithe1n.

The intermittent reclprocating movement ofthe plate 97 is im standards, and which is arranged to return the rock armto its'normal-position as soon.

as the earn 103 hasleft it.

As the cam 31 -is rotated by-the revolutions of the crank-shaft, the cam lug 103 thereon enga ges a roller 104, that is mounted at'the end of-the rock arm 102, whichis pivotally mounted on a screw or headed pin 105, which'is threadedly secured to the side of the standard 3', and tilts the roller end of this rock-arm down, and raisesits opposite end, which is pivotally connected [by .a headed pm 1.06 to the upper end of the slide bar 101. Thisslide bar 101 is-slidably confined in a guideway slot 107, that is formed in a block 108, that is pivotally secured to the side ofthe standard by a-screw 109. .;A guide strap 111 is also secured to .theupper end of the block by the screw109, which strap extends over the adjacent side of the slide bar and holds it loosely. in the, guide slot against accidental displacement from the, guide slotin the block 108. This arnangement-bf guides .torithe slide bar- 101 causesiits loweriendto move up anddown in a vertical pathyand: at its end it is providedwith= 5a; laterally projecting. cam surface l13,'-Whieh as the slide-barr-is raised by the-calming 103'pf the cam 3l-ofithe crank shaftenga'ges; a' projecting knob 114, that is formed ontheadjaoent end of the grip plate 97,-which.-is 'arranged-to-be engaged by the cam when it is moved back so that'it is at the end of its backwardor open stroke movement, and'its teeth are behind the-teeth and are-c nsequently :covered by the teeth 95 0t thegrlp bar 94 of the bundle gripping.

device.- Then=when the cam 113 engages the projectmg knob 114, it'moves the reciprocatinggrip plate inwardly a short: distance, and mpves itsteeth out from under the teeth into the clear space 'betweenthem and up to andagainst the ends of the hooked teeth of the fixed grip ban, closing them around the bundles and looking or gripping them between the fixed-and movable-hooked teeth. The-fixed-gripteeth of the-bar 94 are ar ranged to register exactly with andto pass under-.and=a trifle beyond the teeth of the bundler, whenthebundle gripping device is swung up to meet the handler and shuttle. Consequently the fixed gripping teeth of the bundle gripping device straddle the bundles held in the-teeth of the bundler device, and when thegripping device has reached the endoiititsbundler engaging movement, its reciprocating grip plate .is' moved inwardly by the cam .113, a-ndsurrounds the grips and holds the bundles between its teeth and the teeth-of the fixed. grip bar. Then as the crankshaft continues to rotate, this gripping plate issw-ung downward-into its horizontalfposition over the bristle or hair receiving pan ready for the next operative movement ofithe machine, which is to release the bundles from the bundle gripping and carrying mechanism and deliver themfree to theineedle guide 115, and the plungerneedles, which operation is as follows: When the'gripping mechanism movesdown close to the bristles receivingpan, it strikes a spring plate 116, which normally rests just abovethepan, and is engaged by'the under side of a lugportion 117 of the plate 39 that isformed-into what 1 term a needle and bundle'guide, and is pressed down against the pan, as-will be fully described hereinafter. This-needle and bundle guide 115 comprises the 111 portion 117, that is -formed on the end 0 the plate' 39,- and projects above and below'the plate far enough to form a guide for theneedles 119, which are positioned directly above. it. This needle and bundle guide comprises a plurality of pointed wedge-shaped. teeth arranged in a straight row, there being preferably eleven pointed I and two half-teeth, one at each opposite end portion of the plate, making twelve teeth spaces, between the eleven whole and two half teeth of the needle and bundle gulde, and between each two teeth a guide aperture 120 is formed, which extends vertically down through the lug and forms guide apertures for the needles 115, which move maprocally in them with a close but slidable fit.

There are consequently 12 apertures in the twelve teeth spaces of the needle and bundle guide and there are also twelve teeth spaces and eleven pointed teeth in the bundle gripping device and shuttle, and there are the same number of teeth and spaces in the bundle forming device, and also the same number of teeth and spaces in the comb at the end of the hopper, and there are twelve wire shaped teeth projecting from the points of the wedge-shaped teethof the comb into the hopper in my present machine, and they make brushes having twelve bundles in a row. The bundle gripping device is secured to the outside surface of this needle and bundle uide portion of the hub 28 and plate lie screws 96, which guide portion is machined to receive it, and it is arranged in such relation to the needle and bundle guide portion that they stand parallel to each other, and with the teeth of the gripping device in alinement with the teeth of the needle guide so that the bundles of bristles in the spaces between the teeth of the gripping device lie naturally in the spaces between the teeth of the needle and bundle guide. Consequently when the hub 28 is turned by the crank shaft and its connecting levers to cause its plate portion 39 to swing up from its flat horizontal position over the brush pan holder to its vertical position, the teeth and spaces between them of the bundle gripping device and the needle and bundle guide register with the teeth and spaces of the bundler device, which in turn registers with the teeth and spaces between the teeth of the comb, when the shuttle is at the for- Ward end of its stroke, and the bundles at the time they are embraced and locked to the gripping device lodge naturally in the spaces between the teeth of the needle and bundle guide, as these teeth come up and register in alinement with the teeth of the bundler, but they pass. under them far enough to allow the teeth of the guide to partially surround the bundles in the bundler, while thegripping device is surrounding and looking to them. Thenwhen the needle and bundle guide is moved back down again to its horizontal position over the pan holder, the bundles are held in the gripping device about half way of their lengths, and they lie in the spaces between the teeth of the needle and bundle guide with the center of the lengths of the bristles at the center of the width of the teeth and of the diameter of the needle guide apertures in the spaces -becross-bar;

are reciprocably carried in the cross-head 10- in a cross bar 122, that through the first and greater part of the downward movement of the orosshead is locked to it and travels downward with it,and through the remainingportion of the cross heads downward movement remains stationary, and the crosshead moves down against it. These. sleeves extend into apertures that are drilled entirely through the bar, and the sleeves are hollow throughout their whole length and are secured inthe apertures in thebar by pins 124, which are arranged to-extend into apertures drilled centrally between each alternate pair of sleeves and through the op-- posing sidesof said sleeves, so that when the pins are driven into the aperture they fit into the recesses in the sleeves and thus key them to the cross-bar. These sleeves act as guides for a row of needles 119 that are seecured in apertures in a plate 126-by setscrews 127. The plate is removably secured to the cross head by screws 12 8. There are twelve of these needles and consequently twelve of these sleeves.

The sleeve supporting cross-bar is re'cip rocably mounted in the cross-head of the standards, and is locked to travel with it in the following manner: This cross-bar is supported by two pins 130, which are threaded one at each end into the ends of the These pins extend loosely up into apertures 131 and 132, drilled vertically through the cross-head. The larger hole 131 is drilled down from the top of the crosshead to near the bottom of the cross-head,

where it stops, and the aperture 132 is continued down through the cross-head. The

-pins are provided with slotted heads 133,

that fit loosely and slidably in the holes 131, and the body of the pins fits slidably in the holes 132, and they are turned by a suitable screw driver, which is inserted in the aperture, and they are screwed into the ends of the cross-bar. The pins with their heads extend only part way through the holes iii the cross-head, and above the pins a coiled expansive spring 134'is placed in each aperture, and rests, on thehead of each pin.

The upper entrance ends of the apertures ease-see by the spring 134, whereby the cross bar '122, =the cross-head,- the -inside edge of -eachof with the sleeves; 1-21, is returned to its "norhtheo end blocks 142; which areprovided with j mal positiom 'at 'the end of eachibristle-infully. ,explained, and the downward movea beveled edge 147,-en

The side bars 151 of the auxiliary crosshead, are provided at their upper ends with laterally projecting pins A which are engaged by shoulders A", on" the sides of the cross-head 10, near the upper end thereof, as the cross-head moves upward, thereby lifting the auxiliary cross-head simultaneously with the said cross-head 10. When the cross-head 10 moves down, the auxiliary cross-head 140 moves with it until the teeth of the cross-beam strikes the teeth of theguide plate. The instant the supplemental v cross-head engages the guide plate, the bundles are released from the gripping device automatically.

,The' releasing 'of the bundles from the gripping device is effected as follows: The

plate 39 that supportsthe gripping device is provided with an aperture 154 which enters its end edge, and a pin 155 is slidably mounted in this aperture. A coiled spring 156 is placed in the bottom of this aperture behind this pin, and is arranged-to bear with an expansive pressure against the end of the pin. The opposite end of this pin extends outside of the aperture, andthe end of the plate, and a post portion 163 is formed, which extends across its end at right angles to the in 155, and which preferably forms an integral part of it. This post portion is p0- sitioned between the reciprocating plate 97 and the adjacent edge of the plate 39, and

is providedwith a short projecting vpin 164 that 'is positioned on the post to either bear against the adjacent side of the, reciprocating plate 97 of the bundle gripping device or to fit loosely in an aperture 165' formed in this plate to receive it, in which case the adiacent side of the post bears against tlie side of the reciprocating plate, the post being held under resilient expansive tension against this reciprocating plate by I the spring 156. This spring controlled post and pin mem er I call a lockin -bolt, and it acts to lock the reci rocating plate of the gripping device in its bundle gripping relation to the stationary teeth of the bundle chine the instant the bundle gripping teeth close around the bundles at the bundle formmg device, and remains locked until the needles are ready to push the bundles down through the apertures of the needle guide plate into apertures 166, of the brush back 98, when this plate is released by the withdrawal of the locking pin from the apertures of the plate, which is accomplished automatlcally by the downward movement of the sleeve supporting cross-bar, the end of one of the strips 153 of which engages an upwardly pro ecting spur 167, that is formed on to of the post 163 of the locking bolt. This spur 167 of the locking bolt is provided with a beveled edge, which is beveled to slope backward from the front of the machine while the terminal end'ofthe engaging strip 153 of the sleeve supporting cross-bar is provided with a beveled edge that slopes in the same plane upwardly, and 1s arranged to engage the sloping surface of the spur 167 in such a manner as to move it backward, and consequently the locking bolt against its spring, far enough to move the pm 155 out of the locking aperture of the plate, bythe time the cross-bar has moved down against the cross-beam 150 below it. The instant the plate is released from the pin 155 of the locking bolt, this plate springs outwardly to the right under the tension of a spring 168, which is preferably a wire spring. that is secured at one end to the opposite corner of the plate 39 of the hub 28, from the locking bolt, and is arranged to throw the hooked tooth plateback in the stationary plate of the gripping device in which it is reciprocably mounted.

'When this plate 97 has moved back and released the bundles from the hooked teeth 'of the gripping bar, the guide plate with the gripplng device 1s resting against the brush back 98, which is on the die 169 of the anvil block 170. and the cross beam is about the center of their length. and push them down into and throu h the guide apertures 120. of the guide plate and into and through the apertures of the brush hack, where a wire 171 is run through the brush pan and through the loops of the bristles,

while the needles are held in the brush back for a second or two. as the c oss-head reaches the limit of its downward stroke. and the crank shaft passes its lower centers.

'Which terminate in semi-circular crotches. The needle 5 has similar concaved beveled sides 5 and in the lower end thereof is formed a substantially V -shaped recess 5 which is wider at its open end than the recesses in the end of the sleeve, and termimates in a semi-circular crotch, which is also of slightly greater diameter than those in 'the said sleeve recesses. By this means, the

bundles of bristles engaged by the sleeves are forced into their crotches, and as the needles descend, their V-shaped recesses being wider than those in the sleeves, will insure their surrounding and engaging all of the bristles carried by the sleeves, and delivering them to the pan without loss of any of the bristles.

The brush back illustrated is in the form of a shallow pan and is provided with three rows of bristles or hair receiving apertures 166 for the reception of bristles, and each row holds twelve bundles. The back is also provided with three apertures 172, through its right hand end. These end apertures are positioned each in alinement with one of the rows through the top of the back. The end apertures are arranged and adapted toreceive the end of a wire 171 that is inserted through these holes and extends through the loops formed in the bundlesby doubling or folding them up when the needles engage them at the centers of the lengths of the bundles, and force them down through the guides 120. The needles on the downward stroke of the cross-head of the standards pass entirely through and beyond the ends .of the sleeves into and throu h the row of apertures of the cap that is irectly below them, and they carry the bundles down through'the apertures into the cup portion of the back. At this point, the Wire is inserted in the aperture 172 that is in, aline-. ment with the row of apertures of the top of the cap that the needles are in, and is passed between the end of the needles and the loop endof the bundles.

The instant the needles have pushed the bundles down into the apertures of the back at the end of their downward stroke, they start upward and at the instant the needles have moved upward about an eighth of an inch, the machine is automatically stopped,

by the engagement of the projecting portion of the pawl 41, with the inner face of the arm 42, which releases the said pawl from the clutchon the drivin shaft, and bring the machine to a stop, until the attendant can insert a wire in the back through the loops of the bundles, the slight raising of the needles above the bend in the bundles leaving an aperture in them through which a wire can be easily and quickly inserted.

A coil of wire is supported adjacent to the machine, and its end-is gripped and inserted into the aperture in theend of the back that is in alinement with the row of apertures of the pan the needle and bundles are in, and the wire is pushed through the loop of each bundle and to the opposite end of the back. The wire is then cut close to its outside entrance end, leaving the wire in the back in the loops of the bundles, and it firmly secures them against being drawn out of the apertures of the back when the needles-move upward out of the back. I preferably employ a manually operated device for manipulating the wire, which is ar-.

through which the bolt 174 passes, and a spring 176 is secured tothe under side of the adjacent end of the anvil, its outer end terminating ina semi-circular portion, which bears against the adjacent end of the arm 170, and normally presses its opposite end against the end of a block 17 7 which is secured to. the anvil. When the forward row of'holes 166 is to be filled, the arm 170 is swung toward the rear until it engages an angle plate 178, which is secured to the rear edge of the anvil, and which supports the plate 116, which will be later referred to. When the arm is turned to stand parallel with the anvil, the central row offholes 166 in this position a catch 179 on the end of the arm is sprung into a recess 180, in the adjacent end of the block 177, by the pres sure of the spring 176, whereby the arm is prevented from lateral movement. I To bring the remaining row of holes in alinement with the needle guide, the arm 170 is swung outward until it engages the face of a latch 181, which is pivoted at one end to the outer face of the anvil, its opposite end being provided with a slot 182 through which passes a screw 183, which enters the face of the anvil, and which limits the swinging movement of the latch. I

The latch is normally held at the limit of its upward morement, by a spring 184, which is secured to.the under side of the anvil, and in this position, a portion of the latch exare in alinement with the'needle guide, and

tends above the horizontal face of the anvil, and forms a stop for the arm 170, as clearly shown by Fig. 1. As above mentioned, a piece of wire is passed through the looped ends of each row of bristles before the next row is inserted. In order to remove the back 98, with the three rowsof bristles, from the die block 169, the latch 181 is pressed down and the arm is then swung out to the position shown in Fig. 19. In order that the looped ends of the bristles may not catch in the holes 169 in the die block when the back is removed, I provide means for pushing the bundles from the die block, simultaneously with the removal of the back, as fol.- lows: In the arm 170 beneath the die block, I form a recess 185 of equal width with the said block, and in this recess is placed a plate 186, which has a vertical sliding movement on screws 187, which pass loosely through holes in its opposite ends and are screwed into the said arm. The plate 186 is provided with rows of vertically disposed pins 188, which extend into the holes in the die block and partially through them. This plate is normally flush with the bottom of the arm 170, and to remove the bristles with the back the plate is pushed upward in its recess, and its pins 188 engage the looped ends of the bristles and eject them from the said block, as will be fully understood by reference to Fig. 20.

When the first row of bristles has been inserted in the back, the said row will of coursestand in a vertical position, and in this position the row would be in the path of the guide plate, as it swings down with the next row of bristles, and would therefore be pressed down and crumpled by the said guide plate. In order to obviate this, I employ the pusher 116, previously mentioned, which comprises a plate having guide slots 189, through which screws 190 pass. and enter the angle-plate 178, upon which the pusher is supported. A U-shaped spring 191 is fastened at one end with the angle plate to the anvil, and the other end of this spring terminates in a reduced portion which extends through a slot 192, in the angle plate, and also through a hole in the rear portion of the pusher. This spring exerts pressure in a forward direction on the pusher, which normally causes it to stand in the position shown in Fig. 4, and assuming that the central row of bristles have been inserted in the pan, the pusher is moved to this position by the spring 191, and bends 'the row forward so that it will be out of the path of the descending guide plate. and the ends of the bristles will be engaged and deflected by an inclined plate 193, on the outer -.face of the needle guide on said guide plate. But before the guide plate with the next row of bristles, reaches the limit of its downward movement and rests on the back, the

pusher must be moved back from over the row of holes to be filled, and this is accomplished by a pair of pins 194 which project from the hub 28 of the guide plate, and engage the outwardly turned ends of a U- shaped strip of metal 195, which is secured to the pusher, and as the guide plate completes its downward movement, the pusher reaches the position shown in Fig. 3, and is held in this position until the guide plate is swung up again, moving the pins 194 out of engagement with the ends of the strip 195, and thus permitting the pusher to resume its normal position.

The wire feeding and cutting mechanism is arranged as follows: Secured upon the anvil, so that one of its ends abuts against the block 177, is a plate 196, the opposite end of which extends slightly beyond the adjacent end of the anvil. This plate is provided with a longitudinal dove-tailed groove 197, which extends throughout its length. A block 198 extends a short distance into the outer portion of this groove, and is secured therein by a set screw 199, which extends through the bottom of the plate and engages said block. This block has an offset portion 200, which abuts against the end of the plate. and upon which are mounted three grooved. wire-guiding rollers. Two of these rollers 201, are in line with each other and separated by an intervening space, and the third roller 202 is of.

slightly greater diameter than the other two, and is mounted above and between them, to an adjustable plate 203, which is attached to the offset portion 200 of the block. The grooves of these rollers are in line, and the larger roller extends slightly in between the .other two rollers so as to exert a tension on the wire and straighten the same as it is fed forward. Within the groove 197 is slidably mounted a block 204, to which is attached an operating handle 205, having a slight pivotal movement thereon. The block 204 has a groove 206 in its upper face in line with the grooves in the wire guiding rollers, and at the inner end of this block and intersecting the groove 206. is a screw 207, having a long head, which is slotted from the top down to a point on a level with the bottom of the said groove 206. In this slotted screw is pivotally mounted an L-shaped arm 208, the vertical member of which has a tooth on its lower end which is adapted. to engage the wire which lies beneath it in the slot of the screw. The horizontal portion of the arm 208 lies over and engages a finger 209 on the operating handle, which causes its tooth portion to be slightly embedded in the wire, so that when the plate 204 is moved forward in the groove 197 by the operating handle, the wire is carried with it.

The block 204 is provided with parallel longitudinal holes 210, in which are placed guide 215, inthe form of a screw having a hole through its head through which 'the wire passes. This latter guide is carried by the block 177. On opposite sides of the guide 215, are pivotally mounted blades 216 and 217 respectively, which are provided with wire cutting edges at their ends adjoining the end of the arm 170. The blade I 216 runs parallel with the anvil, and the blade 217 stands at right angles thereto, and

when the handle is pushed forward, the blade 216 is engaged and rocked on its pivot by an inclined face on the end of the finger 209, while the blade 217 is engaged by the end of a projecting member 218, on the handle 205. By this means, the cutting edges of the cutter blades .216 and 217 are caused to sever the wire flush with the end of the bristle holding back, the severing .of the wire occurring when the handle reaches the limit of its inward movement, when it is rocked slightly on its pivot as the end of the projection 218 passes over the inner end of the plate 196, which causes a quick snapping action .of the cutters. The cross-head 213 supports the wire between the wire gripping dog 208 and the guide 215, and as the block 204 is moved forward,

the cross-head engages the block 177 andis stopped, and the block continues, until it engagesthe rear edge of the cross-head,.

when the wire-severing operation occurs. Thus the whole distance traveled by the block 204 corresponds to the length of wire which is inserted in the back between the looped ends of the bristles. The cross-head rods 212 are provided with heads which engage shoulders in the holes in the block 204, and the rear ends of these holes are closed by screws as shown. Backward move ment of the wire is prevented, by a toothed dog 2l9,-which is pivotally mounted between ears 220 on the block 198. This dog is held in contact with the wire by a U- shaped spring 221, the ends of which are coiled around the pivot of the dog, while the connecting member thereof rests upon the top of the dog, as shown.

The machine is automatically stopped by the trip arm 43, as before described, in order that the gripping operation may be inspected; and again by the trip arm 42, to give the attendant time to insert and out the wire. These trip arms are'rocked on a common pivot bolt 42*, to release the pawl 41, by wires 42 and 42 respectively, which extend from the arms and are secured to a lever 42, which is pivoted at one end to a stud 42 which is screwed to an arm 42,

Ill

42 is limited by a headed screw 42 which passes through a hole in the handle portion of the lever and is screwed into the anvil for a portion'of its length. The trip arms are returned to their normal positions by a coiled spring 43', which connects the two arms, as shown in Fig. 2. Sagging of the feed follower 78 of the bristle hopper, is prevented by'an arm 78*, which is secured to the under side of the hopper support, and carries a roller 7 8 at its free end, which bears against the bottom of the said follower. 0 y

The operation of the improved brush filling machine is as follows: The hopper is filled withbristles of the required length, and which stand in a vertical position in the hopper, and the feed follower 78 automatically presses the said bristles forward against the ledge 72 at the end of the hopper, and also against the plate89, the comb 60 serving to split the bristles near the feed end of the hopper in separate bunches orgroups. Assuming that the rocking plate 39 is in a horizontal position, the cam 31 engages the upper end of the arm or lever 33, which is attached to the-crank arm 38 of the rocking plate, and as the said lever is pushed down by the cam, the plate 39 is moved up to a vertical position At the same. time, the cam 42 rocks the arm 44 by which the separator bar 50 is moved across the face of the hopper, and a layer of bristles, which were previously separated into groups or bunches, is separated from gripper. At this point, the knob 103 on the cam 31 engagesthe roller end of the rock arm 102, by which the lever 101 is raised, and its cam face 113 engages the projection 114 on the end of the sliding member 97 of the gripper, and slides the same forward so that its teeth, cotiperating with those of the fixed member 94 of the gripper, engage the bundles of bristles, and when the saidzsliding member reaches the limit of its movement, the hole 165 in its outer end reg isters with the pin 164, on the member 163, which is thrown out by the action of the spring 156, thereby projecting the pin 164 through the hole 165, and locking the plate 97 against the action of its spring 168.

The cam 22 then moves into engagement with the rock arm 2-1, which draws on the lever 26, and rocks the plate 59 to a horizontal position. in which position it rests on the brush back 98, and the guide holes 120 in the plate register with one of the rows of holes in said back. Meantime, the crosshead 10 is descending, with the supplemental head 14-0, which is forced down simultaneously with the cross-head 10, by the spring 157. The supplemental cross-head engages the end of the plate 39, before the crosshead 10 reaches the limit of its downward movement, and as its parallel toothed members 153 straddle the end of the lug portion 117 of said plate through which pass the holes 120, the corner 2 of the outside toothed member 153 engages the inclined face of the projection 167, 011 the springpressed member 163, forcing the said memher rearward. so that its pin 161 is disengaged from the hole 165 in the slidable gripper plate 97, and the said plate is thrown to release the bundles of bristles, by the spring 168. The cross-head 10 continues its downward movement, and the recessed ends of the needle-sleeves 121 straddle the bundles of bristles, which lie across the holes 120 of the plate 39, and double or fold them centrally, and force them down through the said holes 120 until their folded or looped ends stand slightly above the holes in the back, atwhich point the sleeve-carrying bar 122, is stopped by engagement with the member 150 of the supplemental cross-head, and the beveled ends of the trip plates 148 engage the beveled portion 147 of the blocks 1172, at the ends of the bar 141; and the dogs or catches 143, which are carried by said blocks, and which engage the upper edge of the bar 122, are thereby released from said bar, permitting the cross-head 10 to continue and complete its downward movement. This further movement pf the cross-head pushes the needles 119 out through the ends of the sleeves, and the looped bundles are thereby pressed down through the holes 166 in the back 98, thus completing one bristle receiving and inserting operation. At this juncture the machine is automatically stopped in the manner before described, and the handle 205 attached to the wire feeding mechanism is manually moved to insert the wire in one of the holes 172 in the end of the pan, and along through the looped portions of the bundles of bristles until its end contacts with the opposite end of the back, when the. wire is severed in the manner before described. The arm 170 is then moved to bring the next row of holes in the back in line with the needles, and the lever 42 is pressed and the pawl 41 thereby disengaged from the arm 42, and the above operation is repeated, the pins 194: on the hub 28 of the plate 39 releasing the pusher plate 116,

which is then moved forward by its spring 191 to engage and press the row of bristles forward so as to be out of the path of the outer end of the plate 39, on its downward movement. The operation is continued until all the rows of holes\in the back have been filled, after which the back, with the bristles, is removed from the die block 169 by the plate 186, and its pins 188, in the manner previously set forth.
